manual camchain tensioner fitment guide

[VNA]

But how gutted will you be if it fails and you had a manual tensioner in your shed?

You fit a new tensioner and continue as before.

My take is one, tensioner failures today are fairly rare but do happen.  Two, it usually rattles before the chain jumps.  There only seems to be a handful of folks, very few, who have had a chain jump.  Nasty, considering the silly price of parts, and the labour cost if you can't fix it yourself if it happens to you.  It's probably look for another engine time.  But still so rare.

Pilgrim seems to have been hit by lightening twice, and I can understand that he wants now't to do with an auto tensioner.

Would be great to hear from somebody with knowledge of engine design and why all, or the bulk of marks, cars and bikes, have now settled on auto tensioners.  And why race engines are converted to manual, and indeed how they set them up.

Afraid I don't have the answers.  Just not changing until I'm 100% sure it's the right move.
